A shiv, also chiv, schiv, shivvie, or shank, [1] [2] is a handcrafted bladed weapon resembling a knife that is commonly associated with prison inmates. Since weapons are prohibited in prisons, the intended mode of concealment is central to a shiv's construction.
Plants can protect themselves from abiotic stress in many different ways, and most include a physical change in the plant’s morphology. Phenotypic plasticity is a plant’s ability to alter and adapt its morphology in response to the external environments to protect themselves against stress. [ 2 ]
Onion shows a leaf and stem infection. In tobacco black shank affects the roots and basal stem area, but all parts of the plant can become infected. [5] Damping off symptoms can be observed in young seedlings. The first above ground symptom that will be observed is the wilting of plants, which leads to stunting. Roots will be blackened and decayed.
Injury in plants is damage caused by other organisms or by the non-living (abiotic) environment to plants. Animals that commonly cause injury to plants include insects, mites, nematodes, and herbivorous mammals; damage may also be caused by plant pathogens including fungi, bacteria, and viruses.
A crabeater seal injured by a predator. Injury is physiological damage to the living tissue of any organism, whether in humans, in other animals, or in plants.. Injuries can be caused in many ways, including mechanically with penetration by sharp objects such as teeth or with blunt objects, by heat or cold, or by venoms and biotoxins.
Plant callus (plural calluses or calli) is a growing mass of unorganized plant parenchyma cells. In living plants, callus cells are those cells that cover a plant wound. In biological research and biotechnology callus formation is induced from plant tissue samples (explants) after surface sterilization and plating onto tissue culture medium in vitro (in a closed culture vessel such as a Petri ...
William Williams, 24, an inmate at the Federal Correctional Institution (FCI) McDowell, pleaded guilty to possession of a weapon by an inmate at a federal prison, according to a statement from the ...
The oral secretions of herbivores appear to play an essential role in triggering the release of species-specific herbivore-induced plant volatiles. Wounds from herbivores, and mechanical wounds that have been treated with herbivore oral secretions, both trigger the release of higher quantities of plant volatiles than mechanical damage. [4]
